If I didn't go this route I would have to buy: - Selin (or something similar) + dummy MAF - Boost Controller  - some sort of A/F controller  - additional gauges  - and then a custom chipwith this route: - sell my factory ECU - control different maps on the fly for water injection / race fuel - traction control - I like MAP better than MAF - better tuning ability  - don't have to upgrade when I go with a monster build of some sort - satisfy my ultra computer geek nerd tendencies  So with selling my factory ECU and not having to buy a bunch of different piggy back systems it wasn't that much more cash.....and it gives me a lot of room to grow.
